ParaView 5.9 and minimum/recommended QT version

Development
#1

With Qt 5.15 LTS being out since May, it’s probably time to update the QT versions required by ParaView as follows:

  • minimum Qt version: 5.12 LTS
  • recommended Qt version: 5.15 LTS
  • binaries to be built with Qt version 5.15 LTS

Any objections/concerns? If not, we should plan to do this in time for upcoming 5.9 release.

What Qt version do the various distros package by default?

#4

It feels like rendering is faster with Qt 5.15. Did not measured that though.

Unless we get a champion to chaperon this change, this may not happen for 5.9.

#7

ParaView 5.7 builds and works fine using Qt 5.15.1 with a number of deprecation warnings on macOS

#8

Update: ParaView 5.9 will require Qt 5.12. Please see https://gitlab.kitware.com/paraview/paraview/-/merge_requests/4422/diffs?commit_id=24fcce7e8027f48f22dee2396eb828491934838c.

And I noticed that visual studio versions required by paraview has changed to 2017(all previous versions of paraview requires VS-2015). Looks like a big update.

#10

Yes, there is some concern. The latest git clone from 5.9.0 Paraview does not compile with Qt 5.12. At 92%

[ 92%] Building CXX object VTK/GUISupport/Qt/CMakeFiles/GUISupportQt.dir/GUISupportQt_autogen/mocs_compilation.cpp.o

In file included from /path/to/ParaView/5.9.0/buildHere/VTK/GUISupport/Qt/GUISupportQt_autogen/mocs_compilation.cpp:2:0:

QT_INIT_METAOBJECT const QMetaObject QFilterTreeProxyModel::staticMetaObject = { {

There are about 18 such instances of an unrecognized QT_INIT_METAOBJECT in that source file.
This is done in CentOS7 with GCC 7.2.0.

I am testing now if it does compile with 5.15…

Edit: Same issue with 5.15…

For me it’s ok for ParaView 5.9 & Qt 5.15.x on macOS

#12

Eventually I got Paraview to work.
It turned out that I compiled Qt incorrectly.
Once I recompiled Qt, I could compile Paraview as well.
